The OP's post is about ZCF, not ZCI.
Sorry, my mistake.
By way of attonement, this video has an ingenious shop-made fence with a replaceable insert. I thought about doing one, but making those inserts to fit years later seemed too much trouble. So I just have a MDF fence attached to my base (non-moving part) fence via T-slots and as I use it up for angles/bevels I just slide it down a few/several cm.
I bought this from Dennis when he had a batch up for sale (I think he still does, but saves up to have inquiries/orders beforehand)
It is a very nice fence for the KS 60, although, as with KS 120 it quickly interferes with the use of clamps. So does HookedOnWood’s fence too. The slide in ZC for Dennis’ fence is really clever way of solving ease of replacement. I made a fence for my KS 120 in MDF scrap, but removed it’s almost immediately in order to make room for the clamps.
I know Cheese here made minor “adjustments” to the clamp foot with his 8mm fence, even 6mm is obstructing, only just.
